TECHNICAL REPORT
HOLLOW
POLYCARBONATE
A Brief Introduction
Polycarbonate is a very well-known engineering thermoplastic, as clear as
glass and as resistant as steel, it is a carbon derivative that gathers a high
level of mechanical resistance quality, a s w e l l a s o p t i c a l , thermal and
electric. I t u s e f u l i n m a n y d i f f e r e n t e n g i n e e r i n g a p p l i c a t i o n s ,
because of its high versatility, either on flat or curved
situations.
It was discovered in Europe in the early 50’s and its commercial production
started in the late 50’s.

Normally do not cause problems at low concentrations and room
temperature. High temperatures and/or higher concentration will harm
Alkalis
the material.
Acids
Do not attack the material at normal temperatures and concentrations.

Can be partially solvent to the material causing stress cracking. Avoid.
Aliphatic
Usually compatible with the product.
Hydrocarbons
Alifáticos
Halogenated
They are solvents. Avoid.
Hydrocarbons
o
Silicon oil
Normally compatible up to 85
C. Some may contain aromatic
and grease
hydrocarbons and therefore one should avoid them.
Oil and greases
Oil and greases coming from petroleum are generally compatible. Some
additives they contain are not compatible.
Hollow Polycarbonate
It is a flat sheet with an internal hollow cavity, between two external walls,
that restrains the heat exchange from one side to the other, preserving the
temperature of the internal area.
The impact resistance is far better than glass, about 30 times bigger, and
the sheet can be bent without heating being able to stand a bending radio
of minimum 175 times its thickness.
Hollow Polycarbonate sheets have good performance in temperatures
ranging from minus 40°C up to 120°C. In one of its side, a treatment
prevents the damage to the material by the ultra-violet rays, especially from
the sun.
The material is self-extinguishing and do not propagate fire.
By selecting the correct thickness, one can regulate the structure to be
used. By using colored sheets, one can regulate the quantity of light and
heat coming into the ambient. Special length dimension makes it easier to
use less emendation, what avoids easier points for infiltration.
Hollow Polycarbonate is used in general coverage, side closing and sheds,
fair booths, winter gardens, metro stations, sports stadiums, industrial
covering, domes, footbridge, etc. enhancing the natural lightning of the
ambient.
